Sour Cream Streusel Coffeecake — Helen’s Blueberry Buckle for the Fourth

Fourth of July weekend, and the farmhouse was full. David and Karen came down from Montpelier with Teddy and Anna. Sarah couldn't make it — the practice is slammed, summer being prime season for dogs and cats doing things their owners wish they hadn't — but she called and talked for twenty minutes, which for Sarah is practically a haiku.

I grilled. That's what you do on the Fourth. You stand outside in the heat and cook meat over fire and pretend it's different from what humans have been doing for ten thousand years. Hamburgers, hot dogs, corn on the cob done in the husk. The corn is the revelation — you soak the ears in water for an hour, then put them on the grill in their husks. Twenty minutes, turning once. The husks char, the silk steams off, and inside the corn is sweet and smoky and doesn't need butter, though it's going to get butter anyway because this is America and it's July.

Karen is enormous. Eight months along and moving with the careful deliberation of someone carrying a bowling ball in her midsection. She sat in the lawn chair by the garden and directed operations, which is the proper role of a woman in her third trimester — general, not soldier. David fetched things. Teddy fetched things. Anna, who is three and doesn't fetch anything, sat in Karen's lap and ate watermelon with the intensity of a child who has discovered that fruit can be messy and delicious simultaneously.

Fireworks from Burlington were visible from the porch after dark. We sat out there — Helen and I, David and Karen, the kids wrapped in blankets because Vermont nights are cool even in July — and watched the sky light up over Lake Champlain. Frost hid inside. He does not approve of fireworks. He does not approve of anything loud, sudden, or unexplained, which makes him either a very sensible dog or a very Vermont dog. Same thing, probably.

I made a blueberry buckle for dessert. Not a cobbler, not a crisp — a buckle. Cake batter, blueberries folded in, streusel on top. The blueberries are from the farm stand. Ours won't be ripe for another week. Helen's recipe, naturally. The buckle came out golden on top and purple in the middle and we ate it warm with vanilla ice cream while the fireworks popped in the distance and the children fell asleep in their chairs. That's the whole Fourth of July. Food, fire, family, and falling asleep before the finale. Perfect.

The flag is on the porch. It's the same flag Dad hung every year. The grommets are brass and the stripes are faded and I'll put it away tomorrow. Some things you do because they were done before you. That's enough of a reason.

Helen’s buckle has been the ending to more than a few good days around here, and the Fourth felt like exactly the right occasion to let it do its job again—something warm and unhurried to close out the noise and the flag and the children nodding off in their chairs. A buckle is honest food: no pretense, no fuss, just batter and berries and a streusel that goes golden while the rest of the world does whatever it’s going to do. Here’s how I make it.

Sour Cream Streusel Coffeecake (Blueberry Buckle)

Prep Time: 20 min | Cook Time: 45 min | Total Time: 1 hr 5 min | Servings: 9

Ingredients

Streusel Topping

  • 1/3 cup all-purpose flour
  • 1/3 cup packed light brown sugar
  • 1/2 teaspoon cinnamon
  • 1/4 teaspoon kosher salt
  • 4 tablespoons cold unsalted butter, cut into small cubes

Cake

  • 1 1/2 cups all-purpose flour
  • 1 1/2 teaspoons baking powder
  • 1/2 teaspoon kosher salt
  • 1/2 cup (1 stick) unsalted butter, softened
  • 3/4 cup granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • 1/2 cup full-fat sour cream
  • 2 cups fresh blueberries, rinsed and dried
  • Vanilla ice cream, for serving

Instructions

  1. Heat the oven. Preheat to 350°F. Grease an 8x8-inch baking pan and line with parchment paper, leaving an overhang on two sides.
  2. Make the streusel. Combine flour, brown sugar, cinnamon, and salt in a small bowl. Add the cold butter cubes and work them in with your fingers until the mixture clumps into pea-sized crumbles. Refrigerate while you prepare the batter.
  3. Mix dry ingredients. In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
  4. Cream butter and sugar. In a large bowl, beat the softened butter and granulated sugar together with a hand mixer on medium-high until pale and fluffy, about 3 minutes. Add eggs one at a time, beating well after each. Mix in vanilla.
  5. Combine batter. Reduce mixer speed to low. Add the flour mixture in three additions, alternating with the sour cream (flour, sour cream, flour, sour cream, flour), mixing just until no dry streaks remain. Do not overmix.
  6. Fold in blueberries. Gently fold the blueberries into the batter with a rubber spatula. The batter will be thick. Spread it evenly into the prepared pan.
  7. Add streusel and bake. Scatter the cold streusel evenly over the top of the batter. Bake 40–45 minutes, until the streusel is deep golden and a toothpick inserted in the center comes out with just a few moist crumbs.
  8. Cool slightly and serve. Let the buckle rest in the pan for at least 15 minutes before lifting out. Cut into squares and serve warm with vanilla ice cream.
